Attach “了吗” to a verb to ask whether an action or result has been completed; it often implies the speaker is checking a finished state.

Put “多大” before a noun to ask about the size, amount or degree of something, especially in questions about extent.

Use “来自” plus a location, organization or person to say where someone or something comes from.

“对” introduces the target, direction or object of an action or attitude; it is common in sentences that talk about acting toward someone/something.

Put a clause before “的” to describe or modify a following noun; this is how learners build complex noun phrases with background information.
